#26294: call_command doesn't raise same errors from option parsing as running
command

Minimal example:
management/commands/bug.py
{{{
class Command(BaseCommand):
def add_arguments(self, parser):
parser.add_argument('-n', action='store', dest='number', type=int)
def handle(self, **options):
int(options['number'])
}}}
Execute as:
{{{
./manage.py bug -n nan
error: argument -n: invalid int value: 'nan'
}}}
Test using call_command:
{{{
call_command('bug', n='nan')
}}}
Raises a ValueError trying to convert {{{options['number']}}}
The core problem seems to be that kwargs to call_command aren't passed
through the argparse command processing in the way that *args is.
There's a work-around, which is to use the {{{ call_command('bug', '-n
nan') }}} format - perhaps this could be called out in the docs?
